DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In related technologies, water purification equipment mainly relies on aeration, coarse filtration, ultrafiltration, reverse osmosis and other filtration tanks and membranes for multi-stage purification. However, due to climate and energy constraints in high-altitude cold regions, conventional water purification equipment is difficult to operate normally, and traditional water purification technology cannot be applied.

[0033] In view of this, an embodiment of the present application proposes an antifreeze steam purification device.

[0034] See also Figure 1 , an antifreeze steam purification device, comprising an evaporation water tank 8, a purification water tank 6 and a transparent outer cover 3, wherein the peripheries of the evaporation water tank 8 and the purification water tank are both provided with a heat preservation layer 2.

[0035] A water inlet 82 is provided at the top of the evaporation water tank 8, and water to be evaporated is stored inside the evaporation water tank 8. The side walls of the evaporation water tank 8 are inclined, and the angle between the side walls and the bottom of the evaporation water tank 8 is less than 90 degrees; a plurality of photothermal conversion components 4 are provided in the evaporation water tank 8, and the photothermal conversion components 4 are provided through the side walls, and one end of the photothermal conversion components 4 is located at the bottom of the evaporation water tank 8, and the photothermal conversion components 4 are used to absorb the water to be evaporated in the evaporation water tank 8, and to convert light energy into heat energy, so that the absorbed water to be evaporated is heated and evaporated to form water vapor.

[0036] The transparent outer cover 3 is arranged outside the evaporation water tank 8 , and the height of the transparent outer cover 3 gradually decreases from the center to the edge of the evaporation water tank 8 . An evaporation chamber for accommodating the water vapor is formed inside the transparent outer cover 3 .

[0037] The purified water tank 6 is arranged below the transparent outer cover 3 , and the interior of the purified water tank 6 is communicated with the evaporation chamber. The purified water tank 6 is provided with a purified water outlet.

[0038] For details, see Figure 1 The evaporation water tank 8 is arranged above the purification water tank 6. The peripheries of the evaporation water tank 8 and the purification water tank 6 are both wrapped with a heat preservation layer 2 for heat preservation and antifreeze of the whole device. The transparent outer cover 3 covers the periphery of the evaporation water tank 8, and an evaporation chamber is formed inside the transparent outer cover 3.

[0039] The evaporation water tank 8 is used to store water to be evaporated, and a water inlet 82 is arranged on the top thereof, through which the water to be evaporated can be injected into the evaporation water tank 8. The side wall of the evaporation water tank 8 is arranged at an angle, and the angle between the side wall and the bottom of the evaporation water tank 8 is less than 90 degrees, which is an acute angle, so that the side of the evaporation water tank 8 forms a slope surface. A plurality of photothermal conversion components 4 are arranged through the side wall, and the bottom end of the photothermal conversion component 4 extends into the bottom of the evaporation water tank 8, and the top end is located in the evaporation chamber, which can absorb the water to be evaporated in the evaporation water tank 8. When sunlight shines into the evaporation chamber through the transparent outer cover 3, the photothermal conversion component 4 can undergo a photothermal reaction, converting light energy into heat energy, thereby causing the absorbed water to be evaporated to evaporate by heat, forming water vapor that permeates the evaporation chamber. The side wall of the evaporation water tank 8 is in an inclined slope shape, which can effectively increase the illumination area and the evaporation area, thereby increasing the evaporation rate.

[0040] The transparent outer cover 3 is made of a high-transparent plate and is arranged parallel to the side wall of the evaporative water tank 8. The height of the transparent outer cover 3 gradually decreases from the center to the edge. When water vapor condenses on the inner wall of the transparent outer cover 3 to form water droplets, the inclined transparent outer cover 3 can guide the condensed water droplets to slide down along its inner wall.

[0041] The purified water tank 6 is arranged below the transparent outer cover 3. The interior of the purified water tank 6 is communicated with the evaporation chamber, and can collect and store condensed purified water falling from the transparent outer cover 3. A purified water outlet is provided on one side of the purified water tank 6, which can be connected to the water outlet pipe 10 and the valve for convenient discharge and use of purified water.

[0042] Furthermore, the shape of the evaporation water tank 8 can be set to be a prism or a truncated cone. Figure 2 As shown, in this embodiment, the evaporation water tank 8 is a quadrangular pyramid structure with four inclined side walls, and the shape of the side walls is trapezoidal. The four inclined side walls of the evaporation water tank 8 can be arranged with photothermal conversion components 4, and can all be exposed to light. Compared with the evaporation water tank 8 with a rectangular frame structure, it has a larger evaporation area, which is beneficial to improving the evaporation efficiency.

[0043] Further, in order to match the shape of the evaporation water tank 8, the transparent outer cover 3 uses four trapezoidal high-transparent plates, which are respectively arranged parallel to the four side walls of the evaporation water tank 8. The high-transparent plates can be glass plates, polycarbonate plates, acrylic plates, etc.

[0044] Polycarbonate board, also known as polyester board and Capron board, is made of high-performance engineering plastic - polycarbonate (PC) resin. It has the characteristics of high transparency, light weight, impact resistance, heat insulation, and aging resistance. It is an energy-saving and environmentally friendly plastic sheet with extremely excellent comprehensive performance.

[0045] Acrylic sheet, also known as specially treated plexiglass sheet, has high light transmittance, light weight, good weather resistance and acid and alkali resistance, will not turn yellow or hydrolyze due to years of sun and rain, is environmentally friendly and non-toxic, and can be widely used in construction, transportation, medicine, daily life and other fields.

[0046] Selecting glass plate or polycarbonate plate or acrylic plate as transparent outer cover 3 not only has high strength but also good light transmission effect, which is conducive to full utilization of solar energy, and is environmentally friendly and non-toxic, meeting the requirements of water purification. Further, a layer of hydrophilic material is covered on the inner wall of transparent outer cover 3, which is conducive to condensation of water vapor on the inner wall.

[0047] Optionally, the photothermal conversion component 4 includes a water absorption part 42 and a photothermal reaction part connected to one end of the water absorption part 42; a support hole 81 is opened on the side wall of the evaporation water tank 8, and the water absorption part 42 is arranged in the evaporation water tank 8 through the support hole 81, and one end of the water absorption part 42 away from the photothermal reaction part is located at the bottom of the evaporation water tank 8, and the water absorption part 42 is used to transport the water to be evaporated in the evaporation water tank 8 to the photothermal reaction part; the photothermal reaction part is located in the evaporation chamber, and the photothermal reaction part is used to convert light energy into thermal energy.

[0048] See also Figure 2 , a plurality of support holes 81 are distributed on each side wall of the evaporation water tank 8, and the plurality of support holes 81 on each side wall are distributed in an array. The support holes 81 are used to install the photothermal conversion component 4, and can provide support and stability for the photothermal conversion component 4. The photothermal conversion component 4 includes a water absorption part 42 and a photothermal reaction part, wherein the water absorption part 42 is arranged through the support hole 81, and its bottom end is located at the bottom of the evaporation water tank 8, and its top extends toward the evaporation chamber. The water absorption part 42 has a good adsorption effect, and can transport the water to be evaporated in the evaporation water tank 8 along the water absorption part 42 to the top of the water absorption part 42. The top of the water absorption part 42 is connected to the photothermal reaction part, and the photothermal reaction part is located in the evaporation chamber. When sunlight is irradiated into the evaporation chamber through the transparent outer cover 3, the photothermal reaction part can convert light energy into heat energy, causing the water to be evaporated absorbed to the top to evaporate and form water vapor.

[0049] Optionally, the material of the water absorption part 42 includes fiber fabric, and the material of the photothermal reaction part includes graphene or hydrogel.

[0050] For details, see Figure 5The photothermal conversion element 4 is an umbrella-shaped support structure. The material of the water absorption part 42 can be a fiber fabric with good hydrophilicity and good water absorption performance. The photothermal reaction part includes a 3D photothermal reaction layer 41, which is preferably made of graphene or aerogel material, has excellent hydrophobicity and thermal conductivity, and is conducive to improving the evaporation rate. Furthermore, the 3D photothermal reaction layer 41 can be set to black. The 3D photothermal reaction layer 41 is composed of a plurality of closely arranged spike-like protrusions, which can improve the reflection path of sunlight and further enhance the evaporation efficiency.

[0051] Furthermore, in order to avoid position interference between the water absorption parts 42 of the plurality of light-to-heat conversion components 4 inside the evaporation water tank 8, the heights of the support holes 81 on two adjacent side walls may be staggered. Figure 2 As shown, the left side is the first side wall, the right side is the second side wall, and the height of the first row of support holes 81 on the second side wall corresponds to the spacing between the first row of support holes 81 and the second row of support holes 81 on the first side wall.

[0052] Optionally, a seepage hole 61 is opened on the purified water tank 6 , and the seepage hole 61 is arranged corresponding to the inner wall edge of the transparent outer cover 3 , the seepage hole 61 is communicated with the evaporation chamber, and the seepage hole 61 is communicated with the interior of the purified water tank 6 .

[0053] For details, see Figure 3 In this embodiment, the shape of the purified water tank 6 can be regarded as a combination of two rectangular blocks of different sizes, in a "convex" shape, wherein the small rectangular block is located in the upper layer, and the size of the top surface of the small rectangular block matches the size of the bottom surface of the evaporation water tank 8; the large rectangular block is located in the lower layer, and the size of the bottom surface of the large rectangular block matches the size of the bottom of the transparent cover 3. The seepage hole 61 is opened at the edge of the top surface of the large rectangular block, and its position corresponds to the edge of the inner wall of the transparent cover 3. The seepage hole 61 is connected to both the evaporation chamber and the interior of the purified water tank 6. In this way, the condensed purified water flowing down from the inner wall of the transparent cover 3 can flow into the interior of the purified water tank 6 through the seepage hole 61 for storage.

[0054] In this example, the insulation layer 2 is made of a polyurethane insulation board. In other embodiments, the insulation layer 2 may also be made of a nano-aerogel felt.

[0055] Optionally, the thermal insulation layer 2 includes a first thermal insulation board, a second thermal insulation board and a third thermal insulation board;

[0056] The first insulation board is arranged on the top of the evaporation water tank 8, and a first through hole is opened on the first insulation board at a position corresponding to the water inlet 82; the second insulation board is arranged in contact with the side wall of the evaporation water tank 8, and a second through hole is opened on the second insulation board at a position corresponding to the support hole 81, and the water absorption part 42 is arranged in the evaporation water tank 8 through the second through hole and the support hole 81 in sequence; the third insulation board is arranged on the outer periphery of the purification water tank 6, and a third through hole is opened on the third insulation board at a position corresponding to the seepage hole 61, and the third through hole is communicated with the evaporation chamber.

[0057] Specifically, the first insulation board is arranged on the top of the evaporation water tank 8, and a first through hole is opened on the first insulation board at a position corresponding to the water inlet 82. The first through hole is communicated with the water inlet 82 and has a matching size, so that an external water inlet pipe 7 can be connected to introduce an external water source into the evaporation water tank 8.

[0058] The second insulation plate is arranged to fit the side wall of the evaporation water tank 8, and a second through hole is opened on the second insulation plate at a position corresponding to the support hole 81. The second through hole is communicated with the support hole 81 and has a matching size for installing the photothermal conversion component 4. During installation, the water absorption part 42 of the photothermal conversion component 4 passes through the second through hole and the support hole 81 in sequence and extends into the evaporation water tank 8.

[0059] The third insulation board is arranged on the periphery of the purified water tank 6, and may specifically include a first component, a second component and a third component 21, such as Figure 1 As shown, the first component is arranged to fit the bottom of the large rectangular parallelepiped, the second component is arranged to fit the side of the large rectangular parallelepiped, and a fourth through hole can be opened at the position corresponding to the purified water outlet on the second component. The fourth through hole is connected to the purified water outlet and has a matching size, which is convenient for externally connecting the water outlet pipe 10 and the valve, and is conducive to the discharge and use of purified water; please refer to Figure 1 and Figure 4 The third component 21 is a frame-type structure, which can fit the top of the large cuboid and the side of the small cuboid at the same time.

[0060] Since the condensed water droplets need to be stored in the purified water tank 6 after flowing down the inner wall of the transparent outer cover 3, it is necessary to ensure that the seepage holes 61 on the purified water tank 6 are connected to the evaporation chamber. There are at least two following setting methods:

[0061] In the first arrangement, the top of the large rectangular parallelepiped is completely covered by the third component 21, and a third through hole is opened on the third component 21 at a position corresponding to the seepage hole 61, the third through hole is communicated with the seepage hole 61, and at the same time, the third through hole is communicated with the evaporation chamber, so that the condensed purified water flowing down from the inner wall of the transparent outer cover 3 can enter the purified water tank 6 along the third through hole and the seepage hole 61 in sequence;

[0062] The second setting method is Figure 1As shown, the size of the third component 21 is slightly smaller than the top size of the large rectangular parallelepiped, so that the edge of the top of the large rectangular parallelepiped is not covered by the third component 21, and a gap is formed between the outer edge of the third component 21 and the inner edge of the second component. The existence of the gap allows the evaporation chamber to communicate with the seepage hole 61, and the condensed purified water flowing down from the inner wall of the transparent outer cover 3 can flow into the seepage hole 61 through the gap, and then flow into the purified water tank 6.

[0063] Optionally, the outer wall of the second insulation board is parallel to the side wall of the evaporative water tank 8, a baffle 5 is provided at the bottom of the second insulation board, and a water storage tank is formed between the baffle 5 and the outer wall of the second insulation board.

[0064] For details, see Figure 1 , the outer wall of the second insulation board is parallel to the side wall of the evaporation water tank 8, therefore, the outer wall of the second insulation board is also a sloped surface. A baffle 5 is provided at the bottom of the second insulation board, and the baffle 5 is provided around the outer circumference of the second insulation board on the four side walls, and a water storage tank is formed between the inner wall of the baffle 5 and the outer wall of the second insulation board. When the water absorption part 42 of the photothermal conversion element 4 absorbs water too quickly, there may be too much water to be evaporated gathered at the top of the water absorption part 42. Under the influence of gravity, a part of the water to be evaporated will directly drip onto the second insulation board before evaporation, and slide down along the inclined outer wall of the second insulation board, so as to be stored in the water storage tank at the bottom of the second insulation board, and evaporate relatively slowly under sunlight.

[0065] By setting the baffle 5, the unevaporated water can be blocked to prevent it from directly flowing into the seepage hole 61 and entering the purified water tank 6, affecting the purity of the purified water. At the same time, the water storage tank formed by the baffle 5 and the second insulation plate also provides storage space for the overflowed water to be evaporated, facilitating its continued evaporation and avoiding the loss of condensation.

[0066] Optionally, the baffle 5 is arranged perpendicular to the bottom plane of the evaporation water tank 8 .

[0067] In this embodiment, the baffle 5 is a straight plate structure, which is arranged perpendicular to the bottom plane of the evaporation water tank 8, and the height of the baffle 5 is the maximum water storage height of the water storage tank. In other embodiments, the baffle 5 can also be inclined, and the shape of the baffle 5 can also be set to an arc or other suitable shapes.

[0068] Optionally, a partition is provided between the evaporation water tank 8 and the purification water tank 6 , and a heating body 9 is provided in the partition, and the heating body 9 is used to heat the evaporation water tank 8 .

[0069] Specifically, a partition is provided between the evaporation water tank 8 and the purification water tank 6, and the space inside the partition is used to place a heating body 9, which is preferably a self-limiting heat tracing belt or other DC heating body 9, and can preheat the water to be evaporated in the evaporation water tank 8, increase the temperature of the water before evaporation, and thus accelerate the evaporation rate. In addition, the heating body 9 can also be used to keep the purification water tank 6 warm, provide heat energy for the entire device, and avoid the risk of freezing of the equipment.

[0070] Optionally, a photovoltaic panel 1 is disposed on the top of the evaporative water tank 8 , and the photovoltaic panel 1 is connected to the heating body 9 to supply power to the heating body 9 .

[0071] Specifically, the photovoltaic panel 1 is arranged at the top of the evaporation water tank 8, and can convert solar energy into electrical energy when exposed to sunlight to generate electricity. The photovoltaic panel 1 is connected to the heating body 9, and can supply the generated electrical energy to the heating body 9, thereby ensuring the normal operation of the heating body 9.

[0072] The embodiment of the present application adopts photovoltaic power supply and can work without additional power supply, which meets the use needs of remote areas with unstable power supply. It can achieve preheating of evaporated water and insulation of the entire device without relying on national power. It is very suitable for antifreeze purification in high-altitude cold areas, with good purification effect and high efficiency.

[0073] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
